Data bind (currently only android)

• here is a demo of TextView bind.

public class TestTextViewBindActivity extends BaseActivity {

    @BindView(R.id.tv)

    private final Random mRan = new Random();
    private Binder<TextViewBind> mBinder;
    private TextViewBind mProxy;

    private int[] mTextRess;
    private int[] mColorRess;
    private int[] mTextSizeRess;

    @Override
    protected int getLayoutId() {
        return R.layout.ac_test_text_view_bind;
    }

    @Override
    protected void onInit(Context context, Bundle savedInstanceState) {
        initResource(context);
        mBinder = DataMediatorFactory.createBinder(TextViewBind.class);
        //bind group properties to TextView
        mBinder.beginBatchTextViewBinder(mTv)
                .bindText(TextViewBind.PROP_text)
                .bindTextRes(TextViewBind.PROP_textRes)
                .bindTextColor(TextViewBind.PROP_textColor)
                .bindTextColorRes("textColorRes")

                .bindTextSizeRes("textSizeRes")
                .end();
        mProxy = mBinder.getDataProxy();
    }

    @Override
